IN V EN TUR. (bo/Ez J//WES BY United States Patent O LOOSE LEAF BINDERJames cooper, Solvay, N.Y., assigner to Hally & Mcchesney, Inc.,Syracuse, N.Y., a corporation of New York Application March 1, 1957,Serial No. 643,340

Claims. (Cl. 129-23) The invention has as a further objectv a binder ofthe type referred toV embodying av new structural arrangement wherebythe binder has maximum paper capacity for, or in relation to, theover-all thickness of the binder.

A further object resides in the binder having a minimum width inrelation to the width of the sheets, the arrangement being such that noparts of the binder extend beyond the edges of the sheets and nooperating parts of the bin-der extend beyond the width of the sheets.

The invention has as a further object a structural arrangement for theback member including parts so constructed that they may be assembled tovary the thickness of the binder to accommodate a greater or lessnumber, or amount, of sheets.

The invention has as a further object a loose leaf binder wherein theleaf impaling posts are iixedly secured intermediate their ends to theback member, whereby leaves may be removed, or inserted, from one sideof the binder without disturbing the leaf bin-ding at the opposite sideof the binder. This arrangement permits the manufacture of the essentialparts making up the back member structure in volume and yet provides forthe production of binders having varying leaf capacities.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

In the drawings:

Figure 1 is a side end view of the binder shown with leaves or pagesmounted therein.

Figure 2 is a portion of the binder of Figure l opened on one sidethereof.

Figure 3 is a section taken on line 3-3 of Figure 2.

Figure 4 is an element of the loose leaf binder.

Figure 5 is another element of the loose leaf binder.

Figure 6 is a section taken along line 6 6 of Figure 3, with partsremoved.

Figure 7 is an end portion of a section taken along line 7-7 of Figure3.

The back member of the binder, indicated generally at B, includes a pairof complemental channel members 1 superimposed on each other with theintermediate walls of the members lying in a common plane, see Figure 3.The outer leg 2 of the channel members are formed along their free edgeswith a plurality of spaced apart. hinge eyes 3. The inner legs 4 areapertured to receive fastening members, as bolts 5.

A sheet post supporting bar 6 is positioned between the legs 4 of thechannel members and it also is apertured to receive the bolts 5. Aplurality of sheet impaling ICC posts 7 are xedly secured intermediatetheir ends to the bar 6. The posts are spaced along the bar, see Figure2, and are spaced outwardly from the channel members, See' Figure 3. Thebar 6 is formed with apertures 8 for the reception of sheet impalingpins hereinafter referred to.

A keeper bar 9 is mounted on the inner surface of the legs 2 of eachchannel member and is formed with ears 10 extending outwardly throughslots 11 formed in the channel members. The bars 9 are formed with camslots 12 extending in angular relation to the 'axisy of the bars, seeFigure 4. Shouldered rivets 13 are fixed tothe legs 2 of the channelmembers and extend into the slots 12 and serve to mount the bars 9 forsliding movement relative to the channel members.

By' reference to Figure 2, it will be apparent that upon lengthwisemovement ofthe bars 9 in one direction, as upwardly in Figure 2, thebars will be moved inwardly away from the posts 7, moving the ears 10into the channel members 1, this being brought about by the angular camslots 12. Movement of the bars in the opposite direction effectsmovement of the ears outwardly toward the posts 7, in .whichA positionthey overhang the sheets impaledr on the posts. v l i The binder has aback piece shown in Figure 5'. This back piece is rectangular in generalform complemental to the sheet holding structure, consisting of thechannel members, the bar 6 and posts 7. The back piece has end portions18 formed with upstanding flanges 19 which loverlie and close the endsof the channel members, see Figure 1. The anges 19 are formed withapertures 20 arranged in registration with the ears 14 on the keeperbars. A pencil, or the like, may be inserted through the apertures 20 toconveniently actuate the keeper bars into and out Aof leaf retainingposition. The end portions 18 of the back piece are connected by sides21 formed with spaced apart hinge eyes 22 arranged for registration withthe hinge eyes 3 formed on the channel members 1. The opening, definedby the end portions 18 and the sides 21, is closed by a anged plate, tothe outer surface of which is aiiixed a covering of buckram, or leather,23 on which any desired indicia may be printed. This plate is retainedin the back piece by the end flanges 23a offset to overlie the endportions 18, see Figure 7. The inner edges of the ilanges 23a engage aspacer block 24 positioned against the legs 4 of the channel members,see Figure 3.

The binder is completed by a pair of cover members 25 formed with hingeeyes 26 which, together with the hinge eyes 3 on the channel members andthe hinge eyes 22 on the back piece, receive pintle rods 28.

Preferably, a pair of leaf retaining bars 30 are positioned on the posts7 for sliding engagement therewith. The bars 30 have pins 31 extendingthrough perforations in the sheets and through the apertures 8 in thepost supporting bar 6.

The thickness or sheet capacity of the binder can be readily increasedby the use of spacers 35 between the legs 4 of the channel members, inwhich case posts 7 of complemental length are used as well as a backpiece of complemental width.

It will be apparent that the sheet holding structure of my binderembodies a minimum number of parts and that the leaf or sheet impalingposts are rigidly fixed to the back member intermediate their ends,permitting for convenient removal and insertion of sheets when thebinder is opened, and not requiring any special manipulation of the backmember to effect retention of the sheets on the posts, as is the case inloose leaf binders now in used. It will be observed that my binder hasmaximum paper capacity for the overall thickness of the binder, and thatthe binder is of minimum width in relation to the width of the sheetsand, by reference to Figure 6, it will be apparent that the binder doesnot have any operating parts extending beyond the width of the sheets,or movable outwardly therefrom, to position the binder for insertion, orremoval, of sheets.

What I claim is: r

1. A loose leaf binder comprising a back member including a pair ofrearwardly opening channel members having parallel inner and outer legs,said inner legs being aixed together with the intermediate walls of saidchannel members lying in a common plane, a pair of covers hinged to therearward edge of the outer leg of each of said channel members, aplurality of leaf impaling posts xedly secured intermediate their endsto a supporting bar carried by and extending forwardly from theintermediate walls of said back member, said posts being spaced apartalong said back member and being spaced outwardly therefrom, and meanscooperable to retain leaves, or sheets, on said posts.

2. A loose leaf binder as defined in claim 1, wherein said supportingbar is xedly secured between the inner legs of said channel members,said plurality of leaf impaling posts being fixedly secured intermediatetheir ends to said post supporting bar, said posts being spaced alongsaid bar and extending transversely to the bar and in outwardly spacedrelation to the back member of the binder.

3. A loose leaf binder as defined in claim 1, wherein said binderfurther comprises a pair of leaf retaining bars formed with postreceiving apertures for sliding movement on said posts toward and fromsaid post supporting bar to retain a plurality of pages or leaves whichare impaled on said posts, and means carried by the back portion torestrain said leaf retaining bars against removal from said posts.

4. A loose-leaf binder as defined in claim 1, wherein saidlast-mentioned means includes a keeper bar mounted in each side edge ofthe back portion and having an ear extending toward said posts, saidkeeper bar being movable relative to the back portion to move said earinto and out of position overlying the leaves impaled on said posts.

5. A loose leaf binder as defined in claim 4, wherein the means toretain leaves or pages on said posts further includes a leaf retainingbar formed with post receiving apertures for sliding registration withsaid posts, said leaf retaining bar being retained in the binder in saidsliding registration by said ear on said keeper bar.
